TECHNICAL FIELD OF THE INVENTION

The present invention relates to a method and device used for buildingair separation units in a remote location using a mobile manufacturingyard.

BACKGROUND OF THE INVENTION

Air separation units (ASUs) are typically constructed in fabricationshops and then transported to their installation sites via roads andwaterways. As such, the roads, waterways, and bridge clearances create apractical limit on the sizes of the ASUs. However, the market's need forASUs has grown tremendously, with future projections rising even more.As such, the industry is facing a serious challenge in trying to meetthese needs in a cost effective manner.

In the past, if a user required a larger amount of oxygen than what anASU could typically deliver, the installation would just add additionalASUs until the need was satisfied (e.g., two 2,000 tpd instead of one4,000 tpd). While this setup can provide the necessary flows, it createsadditional problems related to maintenance and costs more than operatingone ASU.

Therefore, there is clearly a need for a manufacturing method and devicethat would allow for very large ASUs to be constructed and delivered toplaces of need, particularly when those places are in remote areas thatare not conducive to large trucks. Areas that are landlocked and awayfrom large navigable rivers also suffer from these aforementioneddrawbacks.

DETAILED DESCRIPTION

While the invention will be described in connection with severalembodiments, it will be understood that it is not intended to limit theinvention to those embodiments. On the contrary, it is intended to coverall the alternatives, modifications and equivalence as may be includedwithin the spirit and scope of the invention defined by the appendedclaims.

In certain embodiments, the primary drivers for determining whichcomponents of the ASU could be made remotely can include remotefabrication by inexperienced craft, the transport costs exposure and allthe risks associated with manufacturing in a harsh environment.

In one embodiment, the method and device can be altered or tailored toan individual user's need. For example, the method can includeidentifying a user's requirements for land surface, building sizes,equipment/tooling and utilities which in turn will determine the designand construction requirements, percentage or ratio of the actual overallcolumns and vessels fabrication, schedule and cost. Each of theseModules can be added, combined, or deleted to be adapted to anyproposal, strategies and or combined with any Entity Manufacturing load.

In one embodiment, the Remote Manufacturing Yard (“RMY”) is a mobilesolution for manufacturing of columns that can be used on individualprojects, when needed. The use of the RMY is not applicable for allprojects. For example, the use of the RMY will depend on a certainnumber of factors, a few non-limiting factors could include:

-   -   Site location;    -   Transportation limitations due to infrastructure capacity (most        often bridge capacities or clearances) or limited waterway        access;    -   Economical consideration between transportation and        manufacturing on site;    -   Land and utilities availability locally;    -   Local labor availability and cost; and    -   Project capacity, number and size of column sets;

In one embodiment, the method for fabrication can include variouspacking installations methods. For example, the packing sheets can be(1) inserted directly inside the column shells at the RMY, (2) packagedin segments of 150 mm height and inserted directly inside the columnshells at the RMY, and/or (3) manufactured in blocks (“Frittes”) andinserted directly inside the column shells at the RMY.

In another embodiment, a vertical plate rolling machine can be used forrolling the shells; however, due to size limitations, the methodpreferably includes rolling shells in segments using flux-cored arcwelding (FCAW) in a vertical position for the longitudinal welds. Shellcircumferential welding can also be accomplished using FCAW process in ahorizontal position. This advantageously minimizes joint deformationversus a complete GTAW process and increases overall productivity.

In one embodiment, two stage cores and piping headers for the vaporizerand exchanger will be prefit and supplied in preassemblies usingconventional transport, while the shells and heads will be fabricatedand assembled at the RMY.

FIG. 1 represents a perspective view of remote manufacturing facility 1.In the embodiment shown, remote manufacturing facility 1 includesbuilding one B1 and building two B2 as separate structures; however,those of ordinary skill in the art will readily recognize that theinvention is not so limited. In this embodiment, remote manufacturingfacility 1 includes first structure 2, second structure 4 and outdooryard 10. FIG. 2 provides another perspective view of remotemanufacturing facility 1, which shows various access doors 6, 8 to B1and B2, respectively.

FIG. 3 provides a wide perspective view of building one B1 without firststructure 2 so as to provide a view of the internal stations withinbuilding one B1. Starting from the right side, a delivery truck can beused to deliver plate 22 to building one B1. Each plate 22 is generallyrectangular in shape and can have lengths of about 6 to about 12 meters,thicknesses of about 6 to about 22 millimeters and heights of about 0.5to about 2.5 meters. In one embodiment, plate 22 is made from stainlesssteel material, preferably A240, TP 304/304L or aluminum, preferablyaluminum 5083. After receiving plate 22, plate 22 is moved to platestorage area 20 for storage until needed. Once plate 22 is needed, itcan then be moved to plate rolling area 35 via plate lifting device 30to prep for rolling. Once plate 22 is vertically situated properly ontrolley 24, plate 22 is fed through vertical roller 40 in order to rollplate 22 in a vertical orientation so as to impart a curve and to formhalf course 42. This process is repeated with another plate 22 to createanother half course 42.

The two half courses 42 are then placed on assembly table 50 and matedand welded together using vertical welder 60 to form full course 62. Inone embodiment, the welding is done from both the inside and theoutside. In an optional embodiment, full course 62 can be moved toforming device 55 in order to improve the curvature of full course 62,particularly at the weld locations.

After forming, full course 62 can then be moved to dressing area 70. Inthis area, many items can be installed within and on full course 62 (tobe discussed infra). Scaffolding 72 is erected in and around full course62 to assist, in conjunction with course lifting device 74, withinstallation of the various items within and on full course 62.

Now turning to the left side of FIG. 3, distributor reception table 78receives and stores at least one half of distributor 80. Two halves aremoved onto working table 102 and mated together to form one distributor80. The embodiment shown in FIG. 3 also includes packing fabricationarea 90 for creating packing onsite. In this embodiment, packingfabrication area 90 includes coil holder 92, press module skid 94,washing and cutting skid 96, reception table 98, and transfer table 100.Coil holder 92 feeds continuous metal strips (preferably aluminum) intopress module skid 94 in order to create corrugated packing. From there,the corrugated packing moves to washing and cutting skid 96 to removeoils and other impurities from the corrugated packing, as well as to cutthe corrugated packing into its appropriate strip length. After cutting,the individual packing strips move to reception table 98 where thestrips are organized and grouped together before using transfer table100 to transfer the grouped strips to working table 102 where they arethen put together to form a complete pack.

Bender machine 106 and cutting machine 108 help to create packing band109, which is placed circumferentially around the complete pack in orderto form a complete pack assembly. In certain embodiments, packing band109 includes an adapter that is configured to be picked up by packinglifting device 112. Once the appropriate levels of packing are stacked,packing lifting device 112 moves the packing to packing pallet 114, sothat the packing may be moved to building two B2 for installation withinthe column section. In the embodiment shown, trailer 116 slidesunderneath packing pallet 114 and then raises packing pallet 114 off theground, such that trailer 116 provides full support of the packing.Trailer 116 is then moved to building two B2 via forklift or otherappropriate machine.

FIG. 4 provides a view of an embodiment which includes a plurality ofoverhead cranes 110. In this embodiment, each overhead crane 110 cantraverse a certain point of building one B1; such that the combinedeffect of all overhead cranes 110 is that the entire length of buildingone B1 is covered, thereby allowing for various items and pieces ofequipment to be moved throughout building one B1. Additionally, FIG. 4also depicts movement of the packing from building one B1 using packingpallet 114 and trailer 116.

FIG. 5 provides a wide perspective view of building two B2 withoutsecond structure 4 so as to provide a view of the internal stationswithin building two B2. Starting from the left side, second course 132is brought to column section assembly area 120 and welded to the top offirst course 134 using horizontal welder 130 to form column columnsection 138. In another embodiment, a third course can also be added ifdesired.

In an optional embodiment, column section 138 can then be subjected tonon-destructive testing (not shown) to ensure integrity of the sections.In another optional embodiment, the inner surface of column section 138can be washed 139 to remove oil and other impurities.

Column section 138 is then lifted and placed on moving platform 162,which can be a multi-ton roller platform. Column section 138 is thenmoved to packing and distributor installation area 140, wherein thedistributors and packing from building one B1 are then lifted andinstalled within column section 138 to create packed column section 142.Once the packing and distributor(s) are installed, packed column section142 is then moved from building two B2 to column assembly area 150 inoutside yard 10. Those of ordinary skill in the art will recognize thatpacking and distributor installation area 140 can be in one area orthere could be a separate area to install distributors and anotherseparate area to install packing. The term packing and distributorinstallation area is intended to cover both alternatives.

Once outside, crane 154 is configured to stack a plurality of packedcolumn sections on top of each other so they can be welded together toform column 156. In the embodiment shown, column 156 can be then movedto a horizontal position, prepped for transport, and then loaded on atruck to be delivered to the final installation area, which ispreferably close in distance.

FIG. 6 provides another perspective view of the storage and loadingarea, as well as the vertical rolling and vertical welding. As shown,plates 22 are removed from the delivery truck and placed in platestorage area 20. When a plate is ready to be rolled, plate 22 is liftedfrom plate storage area 20 by plate lifting device 30 and moved to platerolling area 35. Plate 22 is then placed on two or more trolleys 24before being fed through vertical roller 40 to impart the curvature toform half course 42. Half course 42 is then placed on assembly table 50,mated with second half course 42, and then vertically welded together toform full course 62. In one embodiment, mating can include fitting andtack welding. While the embodiments specifically discussed in referencesto the figures reference a half course, those of ordinary skill in theart will recognize that to create a full course, a plurality of partialcourses can be made and then fitted, tacked and welded together to forma full course. As such, any mention of “half” course or “half shell” isnot intended to be limited to only splitting the course into two partialshells. Rather, the scope of the current invention is intended toinclude the making of, and then welding together, as many partialshells/courses to form a full course.

FIG. 7 provides a perspective view of assembly table 50. In theembodiment shown, assembly table 50 includes central support base 200, aplurality of arms 210, second support member 220 and centering guide230. When installed, each arm 210 is attached to central support base200. In the embodiment shown in FIG. 7, arm 210 is generally shaped asan I-beam and is detachably attached to central support base 200 (e.g.,remove nuts and bolts). In another embodiment, arms 210 could bepivotally attached to central support base 200, such that when assemblytable 50 is ready to be packed up and transported, the distal end ofeach arm 210 can rotate toward central support base 200 thereby forminga more compact structure and limiting the footprint of assembly table 50during transportation. In embodiments without the pivot connection, eacharm 210 can simply be detached from central support base 200 andtransported accordingly. In one embodiment, central support base 200 canbe bolted to the floor when in use.

When installed, second support member 220 is attached to a distal end ofarms 210 and is configured to raise assembly table 50 off the ground andto provide support for assembly table 50. In one embodiment, secondsupport member 220 is detachably attached to arms 210. In the embodimentshown in FIG. 7, each second support member 220 is generally shaped asan I-beam; however, those of ordinary skill in the art will recognizethat other shapes could be acceptable. In another embodiment, secondsupport member 220 could be pivotally attached to arms 210, such thatwhen assembly table 50 is ready to be packed up and transported, secondsupport member 220 can collapse either toward or away from centralsupport base 200 such that second support member 220 is substantiallyparallel with arms 210, thereby forming a more compact structure andlimiting the footprint of assembly table 50 during transportation. Inone embodiment, second support member 220 has a fixed length. In anotherembodiment, second support member 220 has a length that can be extended.In another embodiment, the length of second support member 220 can beaugmented to provide leveling on uneven surfaces without having to use ashim.

Centering guide 230 is attached, preferably at a location on arms 210that is directly above second support member 220, such that the weightof the two partial shells is directly above second support member 220during welding. In one embodiment, centering guides 230 can be welded toarms 210. In another embodiment, each centering guide 230 can be movablyconnected to each arm 210, for example slidably), such that centeringguide 230 can move about the length of arm 210, thereby accommodatingpartial shells of varying diameters.

In one embodiment, centering guides 230 are made of stainless steel,preferably stainless steel 304 and are configured to have a taperedopening such that each partial shell can be more easily guided intoposition.

In one embodiment, centering guide 230 can be comprised of two separatepieces, although those of ordinary skill in the art will understand itis not so limited. In one embodiment, the gap formed in the opening isslightly larger than the thickness of the partial shell, such that thecentering guide is not in contact with one or both sides of the partialshell. In one embodiment, the partial shell can be locked into place byinstalling a spacer (e.g., a shim) of a known thickness in between oneof the spaces of the centering guide and the partial shell, and thenusing a second spacer on the opposing side of the partial shell to applyan opposing force to the partial shell, thereby moving the partial shellto the correct location. This allows for the partial shell to be setinto a known inner diameter position.

FIG. 8 depicts a side view of inner scaffolding 73 and outer scaffolding75 being attached to assembly table 50 with full course 62 removed forease of view. In this embodiment, main post 232 is connected to secondsupport member 220 via secondary scaffolding support 234. Extendible arm236 is attached near a top portion of main post 232 and is supported bytertiary scaffolding support 238. Secondary post 240 can be attached totertiary scaffolding support 238 and extend upwards. Secondary post 240can have links 242 which are configured to provide support for handrailsor other similar safety device. Extendible arm 236 extends towards fullcourse 62 in order to provide support for a walkway (not shown) whichlays on top of extendible arm 236, and is configured to support at leastone person, thereby giving said person access to both the inner andouter surfaces of full course 62.

In one embodiment, scaffolding 72 can already be erected and attached toassembly table 50 before full course 62 is dropped into place. In oneembodiment, extendible arm 236 is in a retracted position before fullcourse 62 is in place to allow for more freedom of movement in gettingfull course 62 onto assembly table 50. Once full course 62 is in place,extendible arm 236 can be extended and locked into position.

FIG. 9 depicts a top view of scaffolding 72. In the embodiment shown,full course 62 is not yet in place and assembly table 50 is not includedfor clarity. As shown, scaffolding 72 includes outer scaffolding 75 andinner scaffolding 73. In the embodiment shown, full course 62 would beplaced roughly half way between outer scaffolding 75 and innerscaffolding 73. Additionally, in the embodiment shown, the space betweenthe outer scaffolding 75 and full course 62 is currently empty. However,a substantial amount of this area will be filled in with temporary outerscaffolding once full course 62 is on assembly table 50 and extendiblearm 236 is extended. Similarly, space between the inner scaffolding 73and full course 62 is currently empty. However, a substantial amount ofthis area will be filled in with temporary inner scaffolding once fullcourse 62 is on assembly table 50 and extendible arm 236 is extended.

FIG. 10 provides a zoomed in perspective view of a portion of fullcourse 62 with outer scaffolding 75. In the embodiment shown, a smallgap G will exist between the end of extendible arm 236 when it isextended and full course 62. In a preferred embodiment, the gap is lessthan two inches. The purpose of the gap is to allow for enough room tomove the course in or out of the scaffolding without having to dismantlethe entire scaffolding. In the embodiment shown, outer walkway 82 isalready in place; however, the temporary outer walkway has not be laiddown, which is why there is a blank area BA between full course 62 andouter scaffolding 75. By having this blank area BA, scaffolding 75 canremain in place when the fully dressed full course 62 is moved away fromthe dressing area (i.e., a shell having roundness ring and lifting lugsinstalled). In one embodiment, outer walkway 75 can be selected fromsteel, wood planks, other metallic walkways, or the like.

FIG. 11 provides a side view of course lifting device 74. In theembodiment shown, course lifting device 74 includes four support arms79, with each having plate clamp 76 attached thereto. In situationswhere the user will likely produce shells of differing diameters, courselifting device 74 can include means for diameter adjustment 77. In theembodiment shown, this includes a plate with a plurality of holesdisposed about the plate. Plate clamp 76 can be attached to one of theholes by any suitable connection, for example a Crosby shackle, acarabineer, or the like. Various means for adjustment can include asliding hook, that is configured to slide about the length of the armand lock into place.

FIG. 12 provides a side view of the full course 62 during the dressingstep. As shown, full course 62 was placed in dressing area 70 usingcourse lifting device 74. Scaffolding 72 is already set up and providesaccess for a worker to install roundness ring 250, as well as otherpieces of equipment to the outer surface of full course 62. During thisstep, roundness ring 250 is placed around the circumference of fullcourse 62. A plurality of lifting lugs 252 are attached to roundnessring 250. Lifting lugs 252 allow for packed column section 142 (FIG. 5)to be picked up by the crane. As noted previously, the temporary outerscaffolding can be advantageously removed to allow for full course 62 tobe removed from the dressing area even with roundness ring 250 in place.In normal production facilities, packed column section 142 is movedaround using trunnions that are welded to the packed column section 142.Advantageously, using the lifting lug in accordance with certainembodiments of the invention allow for a reduced height requirement forlifting, which allows for a lower building height. Certain embodimentsof the present invention also require less welding and result in lessplate deformation. Additionally, the roundness ring can cause issueswith access to the trunnions, making them impracticable when a roundnessring is present.

In certain embodiment for shells that will become an upper course (i.e.,the top shell of a column section), clips 253 are added to the outersurface of full course 62 in order to provide support for a hangingplatform in order to give a user access to the top of the column sectionwhen installing the distributor and/or packing FIG. 28 provides a sideview of second course 132 with clips 253 added to its outer surface.FIG. 29 provides a close-up isometric view of one embodiment of clip253. In this embodiment, clip 253 is generally v-shaped; however, it isnot intended to be so limited. It is preferred that clip 253 beconfigured such that when clip 253 is secured to the outer surface ofsecond course 132, clip 253 is operable to support the weight of hangingplatform 254. In one embodiment, clips 253 can be welded onto the outersurface of second course 132. In an additional embodiment, clips 253 canbe welded to either a reinforcement band 251 or clip pads (not shown)instead of being welded directly to the outer surface. For purposes ofthis application, the phrase clips being secured to the outer surface ismeant to encompass all of the above alternatives. Reinforcement band 251or clip pads can be welded to the outer surface of second course 132.Both of these options help to distribute the force applied by the clipsto the outer surface of the second course 132, thereby improving itsintegrity.

In one embodiment, hanging platform 254 includes adapter 255, foot pad256, walkway 257, backing 258, angled post 259, and vertical post 261.Adapter 255 is configured to mate with clip 253, which results in aforce pulling hanging platform 254 toward second course 132 wheneverweight is applied to walkway 257. Footpad 256 can be located at a distalend of angled post 259 and when in use, rests against the side of secondcourse 132. Footpad 256 is configured to disperse the weight of hangingplatform 254 against second course 132 without damaging second course132. In an additional embodiment, hanging platform 254 can also includea vertical extension (not shown) for supporting a roof. In oneembodiment, the vertical extension can attach to backing 258, or it canalready be incorporated within backing 258 and simply be extended frombacking 258. In an additional embodiment, the vertical extension canhave a plurality of arms extending out from the vertical extension, suchthat the plurality of arms are configured to support an external weathershelter that can be used for protection from the environment after thepacked course has been moved outside. FIGS. 34-36 provide various viewsof an embodiment of the external weather shelter.

FIG. 13 a provides an isometric view of the dressing step. In theembodiment shown, shims 260 can be provided such that roundness ring 250can accommodate various course thicknesses. In the embodiment shown,shims 260 are generally L-shaped. Also shown in FIG. 13 a arereinforcement pads 262. Reinforcement pads 262 are attached to the outersurface of course, preferably by welding. Reinforcement pads 262 aredisposed between the course and lifting lug 252 and help to preventtearing of the course when the course is lifted via lifting lug 252.Roundness ring 250 can preferably be dismantled, such that it can beremoved at a later point in time. FIG. 13B provides a close up view oflifting lug 252 and reinforcement pad 262.

FIG. 14 provides an isometric view of packing fabrication area 90. Inthe embodiment shown, both press module skid 94 and washing and cuttingskid 96 are provided on skids, which advantageously allows for bothpress module skid 94 and washing and cutting skid 96 to be shipped aswhole pieces of equipment, and to be at the proper height when inoperation. This is an added advantage of certain embodiments of theinvention since the flooring in the remote manufacturing locations isnot typically a flat and even surface such as in a typical fabricationfacility. In certain embodiments, the skids of press module skid 94 andwashing and cutting skid 96 are configured to allow for leveling inorder to adapt for differences in floor evenness. Additionally, skiddingallows for time savings during installation, dismantling, and shipping.Skids also allow for easier shipping in containers.

FIG. 15 provides an isometric view of washing and cutting skid 96. Inthis embodiment, skid support beams 270 help to provide support andstructure for the skid. In a preferred embodiment, washing and cuttingskid 96 is manufactured in a local manufacturing facility and theninserted into an appropriate shipping container for transport to theremote manufacturing yard. At location, skid support beams 270 can bemaintained or removed depending on the circumstances. As such, washingand cutting skid 96 is configured to be operable with or without skidsupport beams 270. Additionally, skidding allows for time savings duringinstallation, dismantling, and shipping. Skids also allow for easiershipping in containers.

FIG. 16 provides an isometric view of press module skid 94. In thisembodiment, skid support beams 272 help to provide support and structurefor the skid. In a preferred embodiment, press module skid 94 ismanufactured in a local manufacturing facility and then inserted into anappropriate shipping container or shipped without a container fortransport to the remote manufacturing yard. In a preferred embodiment,skid support beams 272 are left in tact during operation. Press moduleskid 94 also can include walls 274, which help to provide an enclosurefor press module skid 94 and reduce some of the noise associated withoperation of press module skid 94. Press module skid 94 can also includeaccess door 276 and strip input 278 and strip output (not shown).

FIG. 17 provides another close up isometric view of an embodiment wherepacking fabrication area 90 includes two press module skids 94 andwashing and cutting skids 96. Two halves of a distributor are moved ontodistributor working table 103 and mated together to form one distributor80. The embodiment shown in FIG. 17 also includes more than one packingfabrication area 90 for creating packing onsite. In this embodiment,each packing fabrication area 90 includes coil holder 92, press moduleskid 94, washing and cutting skid 96, reception table 98, and transfertable 100. Coil holder 92 feeds continuous metal strips (preferablyaluminum) into press module skid 94 in order to create corrugatedpacking. From there, the corrugated packing moves to washing and cuttingskid 96 to remove oils and other impurities from the corrugated packing,as well as to cut the corrugated packing into its appropriate striplength. After cutting, the packing strips move to reception table 98where the strips are organized and grouped together before usingtransfer table 100 to transfer the grouped strips to working table 102where they are then placed together to form packing assembly 101.

FIG. 18 provides an isometric view of packing lifting device 112. In theembodiment shown, packing lifting device 112 includes a plurality oflifting arms 300 extending outward from central member 304 and connectorclips 302 disposed on each lifting arm 300. Packing lifting device 112is configured to lift a complete packing assembly 101 using connectorclips 302 in conjunction with the adapter from packing band 109 andstack the packing assembly 101 onto another packing assembly 101.Preferably, packing lifting device 112 moves packing assembly ontopacking pallet 114 so that a plurality of packing assemblies may bemoved to building two B2 for installation or storage. In one embodiment,packing lifting device 112 is configured such that lifting arms 300 canbe detached from packing lifting device 112 in order to allow for asmaller, more transportable footprint. Other options could includelifting arms 300 that rotate and lock into an open and closed position,which would also result in a smaller footprint. In one embodiment,packing lifting device 112 is configured to be lifted using overheadcrane 110 via lifting point 306.

FIG. 19 provides a close-up isometric view of packing pallet 114 andtrailer 116 without any packing loaded onto packing pallet 114. In theembodiment shown, packing pallet 114 includes pallet support legs 111and packing support structure 113. In one embodiment, packing supportstructure 113 is configured to be able to support the weight of packing,which can be in excess of 34,000 lbs. Support legs 111 not only providesupport for packing pallet 114, but they also advantageously raisepacking support structure 113 off the ground, which allows for trailer116 to be placed underneath packing pallet 114. When packing pallet 114is ready to be moved, trailer 116 can be slid underneath packing pallet114 until lifting members 115 are directly underneath packing supportstructure 113, such that lifting members 115 can be extended, therebylifting packing pallet 114 off the ground. Trailer 116 can then be movedusing any acceptable machinery, for example, a forklift.

FIG. 20 provides a close-up isometric view of column section assemblyarea 120. Second course 132 is brought to column section assembly area120 and welded to the top of first course 134 using horizontal welder130 to form a column section. In another embodiment (not shown), a thirdcourse can also be added if desired. In the embodiment shown, innerscaffolding (not shown) and outer scaffolding 75 are installed such thata user can walk along the inner and outer circumference while horizontalwelder 130 is in operation. In one embodiment, automatic flux cored arcwelding is used. Horizontal welders are generally known in the art;however, in certain embodiments of the invention, horizontal welder 130is configured for flux cored arc welding instead of submerged arcwelding (as is typically done for horizontal welders known heretofore),and is additionally configured to weld smaller diameters than typical,since horizontal welders are typically used for large storage tanks forrefineries having diameters of the order of 40 meters. In anotherembodiment, a separate horizontal welder 130 is used for inside andoutside welding.

In certain embodiments, a backing strip is not used when making thewelds. This is because backing strips can cause an accumulation ofliquid oxygen and/or hydrocarbons in the area between the backing andthe course, which can result in a possible fire hazard. However, incertain embodiments, space on the inside of the course is at a premium,which prevents a user from being on the inside of the course duringwelding. For example, for certain courses that will enclose the mainvaporizer, there can be instances when space does not allow for a userto be inside during welding, such that a backing strip can be used.However, as noted above, the use of a backing strip can lead to possiblesafety issues.

In order to reduce the risk associated with liquid build-up, drainageholes can be drilled into the backing strip prior to installation. Inone embodiment, holes can be drilled at various locations, for exampleevery two meters of back strip. In another embodiment, the location ofeach drainage hole can be at a point that will be above thecircumferential weld, such that any liquid that falls between thebacking strip and the course will be able to travel through the drainageholes. If the entire hole were below the circumferential weld, then theliquid would not be able to drain from behind the backing strip andbecome trapped. As such, it is preferable to have drainage holes locatedon the backing strips in a proper location such that the drainage holesare configured to allow drainage of any trapped liquid during operation.Drainage holes can be round, oblong, or any other shape that allows fordrainage of the liquid.

FIG. 21 provides a close-up isometric view of optional cleaning station320. In the embodiment shown, a user can be raised and lowered withincolumn section 138 via scissor lift 322 such that user can wash theinside of the welded column sections to remove oil and/or debris. Incertain embodiments, welded column sections are raised up off the floorvia cleaning station support 324, which gives user access to the insideand outside the welded column sections.

FIG. 22 provides an elevation view of packing and distributorinstallation area 140, wherein the packing and distributors frombuilding one B1 are then lifted and installed within column section 138using packing installation device 141. In one embodiment, distributor 80is installed first with packing assembly 101 being installed on top ofdistributor 80. In one embodiment, packing installation device 141 caninclude cage 143 and adapter ring plate 145. Cage 143 is securelyattached to adapter ring plate 145. Adapter ring plate 145 can have alocking mechanism that is configured to engage with adapter 147 therebytransferring a lifting force to packing assembly 101.

In certain embodiments, the packing can be installed band by band, as anassembly (i.e., the entire circle), or in portions. When in portions,the packing would arrive in boxes, a worker would enter the inside ofcolumn section 138, the boxes would be lowered into column section 138and the worker would then remove the portions from the box and manuallyfill in the area until completed. Once the packing and distributor(s)are installed, the packed column section is then moved from building twoB2 to outdoor yard 10.

FIG. 23 provides one embodiment for moving the packed column sectionsfrom building two B2 to the outside yard. In this embodiment, winch 160is used to move packed column section 142. Packed column section 142 islocated on top of movable platform 162, with movable platform 162 beingconfigured to support the weight of the packed column section 142.Additionally, movable platform 162 is configured to be attached to acable from winch 160, such that winch 160 can cause movable platform 162to progress towards winch 160. In one embodiment, movable platform 162can include a plurality of multi-ton rollers (340 in FIG. 24) which areadapted to mate with a set of rails 166 disposed on the ground such thatrails 166 help to guide movable platform 162 towards winch 160 withoutmovable platform 162 drifting left or right. In one embodiment, winch160 is secured to the ground or flooring. Rails 166 can be located ontop of the ground, or they can be recessed in the ground, such that theflooring has a generally flat surface.

FIGS. 24 a-d provides an embodiment of multi-ton roller 340. In theembodiment shown, multi-ton roller 340 includes a set of roller guides342, which are configured to mate with rails 166. While multi-tonrollers are generally well known and can be purchased from Hilman Inc,certain embodiments of the invention use multi-ton rollers that havebeen adapted such that they are configured to mate with rails 166 viaguides 342 and can be attached to movable platform 162 via top plate370. In one embodiment, multi-ton roller 340 can include body frame 372,top plate 370 secured to body frame 372, a plurality of individualrollers 374 movable about load-bearing member 376 and located withinbody frame 372, wherein rollers 374 are configured to support body frame372 and facilitate longitudinal movement of body frame 372 along thelength of rail 166. Guides 342 help to prevent lateral movement of themulti-ton roller during movement along rail 166.

FIG. 25 a, FIG. 25 b, and FIG. 25 c provide top views of movableplatform 162 in various configurations. In the embodiments shown,movable platform 162 includes base frame 170, movable beam 172, andtable posts 174. As shown by the arrows, movable beam 172 can be movedabout base frame 170, such that movable platform 162 can accommodatesupport bases 180 of different diameters, which allows movable platform162 to be highly adaptable for different column section diameters. Inone embodiment, table posts 174 extend upward (i.e., out of the paper)such that the packed column section is elevated from the ground, therebyallowing a user access to the underside of the packed column section. Inone embodiment, support base 180 has a washer-like shape, such thatsupport base 180 has an outer and inner circumference and a height. Inanother embodiment, table posts 174 are configured to mate with notchesin support base 180. This advantageously helps to stabilize support base180 on top of movable platform 162, particularly when being moved or inthe event of severe wind. In certain embodiments, support base 180 ismade from structural carbon steel. Support base 180 helps to distributethe weight of packed column section 142 more evenly, and thereby reducethe risk of damage to the shell of packed column section 142. In certainembodiments, packed column section 142 can be secured to support base180, preferably using welding stiffener. However, those of ordinaryskill in the art will recognize that the shape can be any that willallow for placement of a packed column section and provide the neededsupport, such as a nut, hexagon, octagon, etc. . . . as non-limitingexamples.

In one embodiment, the portion of the column that will house the mainvaporizer at the bottom of the low pressure column can be placed onmovable platform 162 without using support base 180 duringtransportation from building two B2 to column assembly area 150.

FIG. 26 a provides a top view of yard leveling base 185 and FIG. 26 bprovides a side view of yard leveling base 185. Yard leveling base 185can be used to assist with creating a level surface for which to stackcolumn 156 on top. In normal manufacturing facilities, yard levelingbase 185 would not normally be used as the flooring of the permanentshops is made to be level. However, there will be certain situationsencountered where the floor of outdoor yard 10 of remote manufacturingfacility 10 will not be substantially level. In these cases, a certainamount of variance in leveling could cause uneven stresses on column156, and ultimately lead to either unsafe conditions and/or an off-speccolumn. Therefore, yard leveling base 185 can be used to alleviate someof these problems. In the embodiment shown, yard leveling base 185 has awasher-like shape, such that yard leveling base 185 has an outer andinner circumference, and a height. However, those of ordinary skill inthe art will recognize that the shape can be any that will allow forplacement of a packed column section and provide the needed support,such as a nut, hexagon, octagon, etc. . . . as non-limiting examples. Incertain embodiments, the entire circumference does not have to beresting directly on a surface; however, it is preferred to have as muchof the bottom circumference resting on a surface in order to minimizedeformations of the shell due to the weight.

In one embodiment, yard leveling base 185 includes a plurality ofnotches 186 spaced about the circumference that are configured to allowfor lifting system 192 to be placed within notches 186 and raise thelevel of that area, such that leveling can be achieved. In oneembodiment, lifting system 192 can be selected from the group consistingof a hydraulic lift, a screw lift, an air lift, and combinationsthereof. A jack would be an example of a hydraulic lift. In oneembodiment, yard leveling base 185 can accommodate a weight of about 100metric tons. In one embodiment, shims 188 can be installed at a locationnear notches 186 and underneath yard leveling base 185 after beingraised in order to maintain the leveling after the jack is removed. Inone embodiment, a clamp system can be used to secure yard leveling base185 to the ground. In one embodiment, anchor bolts or their mechanicalequivalents can be used. In one embodiment, a plumb line can be used toassist with leveling. In one embodiment, a plumb line is attached to anupper portion of packed column section and the plumb line is allowed tohang freely. The distance of the plumb line from the top of the packedcolumn is a known value, and the yard leveling base is adjusted untilthe measured distance of the plumb line near the bottom of the packedcolumn matches the known distance.

FIG. 27 includes several views of one embodiment of trolley 24. In theembodiment shown, trolley 24 has support body 25, lifting arm 26, plateholder 27, pump handle 28, and wheels 29. In one embodiment, plateholder 27 is rotatably attached, via a support bracket, to lifting arm26 such that when lifting arm 26 moves between its lowermost anduppermost position, plate holder 27 rotates relative to lifting arm 26thereby keeping any plate 22 being held by plate holder 27 in asubstantially vertical position. Pump handle 28 is configured to causelifting arm 26 to move, which, in one embodiment, is similar to a pumpjack. Support body 25 provides support for trolley 24. In oneembodiment, wheels 29 are connected to support body 25. Wheels 29 arepreferably a heavy duty kingpin style caster. Plate holder 27 isconfigured to receive plate 22, secure plate 22 in place, and thensubsequently release its grip on plate 22 so that plate 22 can beremoved from trolley 24 following rolling. In one embodiment, plateholder 27 includes toggle clamp 31, plate clamp 32, and clamp mountinghex nut 33. Toggle clamp 31 is configured to provide course adjustmentto plate clamp 32 and clamp mounting hex nut 33 provides more fineadjustment. In order to lock plate clamp 32 into place, clamp mountinghex nut 33 is turned to adjust the set position of plate clamp 32 andtoggle clamp 31 is then moved to cause plate clamp 32 to move towardplate 22 and hold plate 22 firmly in place.

In embodiments in which the remote manufacturing facility will notproduce its own packing onsite, the packing can be manufactured in anormal manufacturing facility. In instances where the diameter of thecolumn is small enough, the packing can be broken up into sections andplaced in a corresponding box for shipment. As shown in FIG. 30, anentire level of packing can be transported in eight different boxes.Each box 400 is specifically configured to hold a certain portion of thepacking. In the embodiment shown, the box has supports 402 built intothe box in order to keep the packing in place and protected duringshipment.

There could be instances where the diameter of the packing is too longfor shipment, and the packing cannot be made onsite at the remotemanufacturing facility. Additionally, in embodiments in which thepacking is installed in the column section by box loading, boxes havingthe packing strips near the middle will be too large to place within thecolumn section. FIG. 31 provides a solution to this problem. In thisembodiment, the length of the shipping box for certain portions of thepacking is actually less than the length of the strips to be placed inthe box (and therefore smaller than the diameter of the column section).In order to accommodate the extra length of the strip, the box containscurved supports 404 that cause the strip to form a wave, whicheffectively shortens the strips apparent length, thereby allowing stripsthat would normally be too large for the box to be shipped in a box thatis properly sized for transit, and in certain embodiments, placementwithin the column section during installation.

In certain embodiments, shipping costs can be further reduced byarranging the individual packing strips in a particular way within theboxes. When packing strips are usually installed in boxes, the packingstrips are generally oriented the same way as they would be wheninstalled within the column. However, certain embodiments of theinvention can include the step of rotating/flipping every other packingstrip 180 degrees such that the profiles of successive packing stripsare now matched up with each other. FIG. 32 provides an example. Asshown during installation, first packing strip A and second packingstrip B have offsetting profiles. While this profile setup isadvantageous during operation, it can be wasteful during shipment. Asshown, the resulting height H_(I) during installation of two packingstrips A,B is h_(A)+h_(B).

However, in the embodiment shown, after packing strip A is flipped 180degrees, its profile matches the profile of packing strip B. Therefore,when the packing strips are placed on top of each other, the overallheight during shipping H_(S) can be reduced since the height of packingstrip B is eliminated and only the thickness of B contributes to theoverall height of the two packing strips. In typical packing, the heightof each packing strip is substantially greater than the thickness of thematerial, and therefore, a substantial savings in space can be achievedin certain embodiments of the invention.

For embodiments in which vaporizer 350 is manufactured in a normalmanufacturing facility (i.e., not at the remote manufacturing facility)and is too big to transport, main vaporizer 350 can be fullymanufactured and then cut into at least two sections: lower stage 352and upper stage 354. In one embodiment, all the work for both lowerstage 352 and upper stage 354 can be fully finished in the normalmanufacturing facility with the exception that certain process lines andtransition joint (TJ) between aluminum and stainless steel can be fullyfinished in the normal manufacturing facility and delivered to theremote site as one component, with subsequent welding at the remotesite. Advantageously, certain embodiments of the invention allow for acondenser that would normally be too large to be transported, to beshipped to the remote site, while also maintaining the highestproduction standards.

FIG. 33 provides an embodiment of the invention in which main vaporizer350 is installed at the remote site. In the embodiment shown, (startingfrom the right side) lower stage 352 (two set of four core assembly) isinstalled first and fit and welded to bottom head. Course lifting device74 then brings first course 356 (e.g. full course 62) and lowers firstcourse 356 over and around lower stage 352. Second course 358 is thenbrought and fitted and welded to the top of first course 356. Upperstage 354 (two set of 4 core assembly) is then installed to top of lowerstage 352. Two more courses 360 and 362 can then be fit and weldedappropriately such that main vaporizer 350 is now enclosed within acolumn section. In another embodiment, a column section (e.g., two ormore courses already welded together) can be installed, as opposed toinstalling one course at a time.
